Emmanuel Grumbach 984ecb9293 iwlagn: fix a race in the unmapping of the TFDs
While inspecting the code, I saw that iwl_tx_queue_unmap modifies
the read pointer of the Tx queue without taking any locks. This means
that it can race with the reclaim flow. This can possibly lead to
a DMA warning complaining that we unmap the same buffer twice.

This is more a W/A than a fix since it is really weird to take
sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp
the locking model in the transport layer.

Johannes Berg d36120c625 iwlagn: stop interrupts when suspending
Occasionally, the device will send interrupts
while it is resuming, at a point where we are
not set up again to handle them. This causes
the core IRQ handling to completely disable
the IRQ, and then the driver won't work again
until it is reloaded/rebound.

To fix this issue disable the IRQ on suspend,
this will cause us to only get interrupts
again after we've setup everything on resume.

802.11 says:
"Sequence numbers for QoS (+)Null frames may be

However, if we use the normal counters then peers
will get confused with aggregation since there'll
be holes in the sequence number sequence.

To avoid that, don't assign sequence numbers to
QoS Null frames.

Johannes Berg 3bde2b68cf iwlagn: update beacon smarter
Updating the beacon every time right after one was
transmitted is pointless, most of the time we might
not even have to update it. We will update it every
time it changes, which includes from set_tim(), a
callback iwlwifi didn't implement so far.

This also reduces latency for clients, previously
we would update the beacon right after the previous
one was transmitted, and then a TIM change would
only take effect after that again -- updating the
beacon right after the TIM changes makes the TIM
change go out to the air faster.

Felix Fietkau 846d936350 ath9k_hw: fix a regression in key miss handling
The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code
to only report key miss errors if a MIC error wasn't reported.
When checking the flags in that order in the MAC code, it might miss some
real events, because the value of the MIC error flag is undefined under
some conditions.

The primary issue addressed by the previous commit is making sure that
MIC errors are properly reported on the STA side. This can be fixed in
a better way by adding a separate rx status flag for key miss and
ignoring it for multicast frames.

This fix slightly improves stability in AP mode on some older hardware,
like AR9132.

The code for handling various restrictions concerning regulatory limits,

EEPROM parsing implementations, making it hard to review.

This patch partially cleans up the mess by unifying regulatory limit
handling in one function and simplifying handling of antenna gain.
It also removes unused transmit power scaling arrays from the EEPROM code,
which belonged to an unimplemented API that isn't supposed to be in
the driver anyway.
